METALLIC WINDOW AND DOOR FRAME I Originl Filed Jan. 3, 1938 2Sheets-Sheet Z Hum 96 W i0 and method of manufacture Patented Oct. 29,1940 UNITED STATES PATENT OFFICE 9 Claims.

past, there has been an inmanufactured and sold for use on smalldwellings To satisfy this demand a number have developed and are at tothe trade, metallic frames and the like. of manufacturers present timeoffering in which the various parts, such as the head,

jambs and sill are individually stamped or cast and finally securedtogether at the corners by providing overlapping and/or interlockingportions which are secured together by spot welding and other means.While these frames possess many advantages not found in the older forms:5 of wooden frames and sashes, they are still open to the objectionthat their cost is prohibitive due l to the complications encountered intheir manufacture. It is, principal object .of the present invention toprovide an article in the form of window-and door frames in which theparts forming the head, jambs and sill are of substantially identicaland uniform cross-section and which, because of this characteristic, canbe formed from a single strip of metal and thus greately simplify themanufacturing operations and provide a frame for windows and/or doorsconstructed entirely of metal that can be manufactured at a pricecompetitive with the wooden frames heretofore supplied for this purpose.

Another object of the invention is to provide a new and novelimprovement in ,metallic frames which will facilitate the manufacture ofthe frames from a continuous preformed strip of sheet metal.

A further object of the invention is to provide 1 an improved method offabricating metallic frames for double hung windows and doorways 50which will greatly simplify the manufacturing operations by eliminatingthe time consuming effort which is now necessary to properly align andsecure the top, jambs and sill of the frame together in accordance withthe prior art I methods.

Divided and this application January Serial No. 251,330

Other objects and advantages of the invention will be in part pointedout hereinafter and in part evident to those skilled in the art as thedescription thereof proceeds.

For a better understanding of the reference should be had to theaccompanying drawings wherein there is shown, by way of illustration andnot of limitation, preferred embodiments thereof.

Figure 10 shows a structed in accordance with the present invention andfrom which a metallic window sash may be constructed, and

Figure 11 is a fragmentary view showing a strip of the latter type asbending operation to complete a corner similar to that illustrated inFigure 10 of the drawings.

The novelty of the present inventionin addition to residing in theproduction of a metallic frame forming strip conmitred prior to the 50frame from a single piece of sheet metal in a I novel and inexpensivemanner also resides in the particular characteristics of the strip whichwhen mitred in accordance with the invention provide two spaced anduncut portions upon which the strip may be bent to bring the ad- Jacentportions thereof at the corners into exact meeting relation by virtue ofthe fact that the two spaced uncut portions function as bendableindexing ties in a manner similar to that obtaining with a door hingedupon two spaced hinges.

In my prior above identified disclosure, wherein the frame is disclosedas formed with a single outwardly extending side flange, means must beprovided to bring the adjacent parts of the frame into meeting relationduring the bending operation, whereas with the present invention thestrip can be easily bent after being mitred without requiring anyspecial means to insure a meeting of the inner light opening donningportion of the frame or the side walls thereof into exact meetingrelation. g

The particular frame structure illustrated in Figures -1 and 2 of thedrawings is of simple conand an upper sash II, the light openingdefining wall II in this embodiment of the invention is shown moreclearly in Figure 2 as having a contrally disposed smaller channel itthat provides an inwardly extending rib or parting strip against whichthe sashes l4 and it are adapted to be held and slide.

light opening of the frame is also shown as havin it into whichremovable retaining 2i! are respectively inserted. When strips l I anding strips I9 and 20 are inserted in their respec tive channels l1 andII it will be seen that the sashes H and I5 will each be provided withspaced guides between which they may freely slide in accordance with thepractice in the conventional double sash window frames.

At this point it will be evident that while the sash retaining strips IOand 20 are shown as provided in the head or top of the window frame it,the strips may, if desired, be omitted at this point and at the bottomof the frame, if desired, the channels l1 and I! may be provided with afiller strip which extends flush with the inside surface of the lightopening defining wall ll of the window frame I0. Further it may be saidthat while the channels I! and ii are not necessary at the top or sillof the frame, since they do fully justified as it makes possible theconstruction of the frame from a continuous single strip of sheet metalof uniform cross-section.

the strip is mitred and ,inside and out two oppositely disposedchannels" "and" meeting relation. In this figure of the drawings themitre out, designated by the numeral Ii, is shown as extending throughthe inner light opening defining wall H of the frame and into the insideand outside flange forming portions II and II thereof to a point closelyadiacentthe outer edges of these latter flange forming portions wheresmall uncut portions of these flanges, deslation when the mitre cuts IIare fully closed. To complete the frame there then only remains thenecessity for securing the meeting ends of the strip which complete therectangular frame. vWith a frame of this character the builder need onlyprepare the wall of the building with properly spaced stringers and/orstudding between the side forming flanges II and If to which the framecan be finally nailed and/or otherwise socured.

In Figures 4 and 5 of the drawings there is illustrated of the inventionwhich I4, is shown as having a relatively wide central channel 2! whichprovides what may be otherwise termed an inwardly extending cleat 20against which a door, designated by the numeral 21, may be mounted. Theclcat fl is made to extend out sufliciently far from the wall 14 of theframe to form a stop for the door and at the same time this cleat is soproportioned in width that it will not provide an obstruction at thesill of the frame which, as contemplated by the invention, is of thesame cross-section as are the lambs and top of the In this embodiment ofthe invention the mitre cuts it are shown as extending through theportion 24 and the olcat ll of the frame and into the spaced portions IIand fl which form respectively the While which is particularly adaptedfor window frames having double hung sashes.

After the strip hasbeen rolled into this frame into right angled meeting relation. TheConfiguration it is Provided w mitre cuts, novelty here, like in thepreviously described which extend through the light opening definingframes, resides in the arrangement of two uncut wall 30 and into theside flanges 3| and 32 to portions in the strip at points spacedlaterally a point beyond the ribs 34 and 35 in these porfrom each otherand outwardly beyond the light tions of the frame and thus leave twospaced 1mopening defining wall ofthe frame so that when out and bendabletie portions 31 and 38 which, as the strip is bent upon these uncutportions the 16 has b en he b pointed Out, function to inner and sidewall surfaces of the frame will be 1 retain the a a n portions of thestrip together brought into exact meeting relation when the and bringthe surfaces thereof into exact meetstripis bent to close the mitrecuts. the relation, as illustrated in Figure, 'l of the It will be ofimportance to note that this strucd a when the Strip has b bent uponture provides two transversely aligned connecting 20 these uncut tie D tto Complete the ties at each mitre cut and that, since each mitre 20When the Window f am s constructed from cut extends entirely through thechannel base or s ip f m with the ribs qfiias last light openingdefining wall and outwardly into above described, ese ribs in addlhoh tothe two opposed side flanges, each tie will be disviding a rein in theSides of the frame posed inthe plane of the side flange of which it asat these points also furn h a heading t which is a part.
